Application filed November 2, 1928.

This invention relates to a beverage dispenser of the particular type involving a display receiver', preferably transparent, into which beverage is discharged and a dispensing tube mounted in the side wall of the receiver for diverting beverage from inside to a point outside the receiver, and has for its object to afford a simple, practicable and especially adapted to structures where the dispensing tube is formed of glass or similar material.

The invention has for a more specific purpose to afford a structure in which the dispensing tube can be quickly and easily removed for cleaning, or for replacement if broken. Y

Another object of the invention is to afford a dispensing tube with provision for sealing the passage in the tube to prevent ingress of air therethrough, while still permitting the tube to be made in one piece and to be instantly removed from the receiver without necessitating any change in the position of the latter.

lith these ends in view, the invention consists in the construction and arrangement of parts that will appear clearly from the followingdescription when read in conjunction with the accompanying drawings, the novel features being pointed out in t-he claims following the description.

In the drawings Figure l1 is a side elevation of a beverage dispenser constructed in accordance with one practical embodiment of the invention;

Figure 2 is a vertical sectional view showing the dispensing tube in its normal outer position;

Figure 3 is a similar view showing the dispensing tube when moved inwardly to dispensing position;

Figure 4 is a sectional view on line 4 4 of Figure 2;

Figure 5 is a view similar to Figure 2 illustrating a modiiied form of dispensing tube;

Figure 6 is a view similar to Figure 3 with the modified form of dispensing tube, and

Figure 7 is a sectional view on the line 7-7 of Figure 5.

Referring more particularly to the drawings, in which like reference numerals refer to the same parts throughout the several BEVERAGE DISPENSER.

views, 1 designates al display receiver which is preferably transparent and into which beverage may be discharged from a pipe 2 that is suitably connected with a beverage container 3 located in the cabinet 4. 5 is a motor operating a pump 6 which forces the beverage upwardly from the container 3 through pipe 2 into the display receiver from which it flows back to the container 3 by gravity, in accordance with known structures in this art.

The beverage is drawn olf through a dispensing tube that is slidably mounted in the side wall of the display receiver 1 so as to bring the inner end of the tube into the path of the beverage, the pressure of the latter serving to carry it through the dispensing tube when so positioned. In the present embodiment, the dispensing tube is indicated at 10, being preferably constructed of glass and slidably mounted in a bushing 11 extending through an opening in the wall of the receiver and held by a collar 12 on the inside having threaded engagement with the bushing 11 and a sleeve 13 on the outside that is held against the outer surface of the display receiver by the nut 14 threaded on the bushing 11.

The bushing 11 is interiorly recessed to receive a spring 15, the outer end of which engages a collar 16 mounted on the dispensing tube and resting against the enlargement 17. The spring 15 acts to hold the dispensing tube normally in its outer position, as shown in Figure 2, and to dispense the beverage, the

tube is pushed inwardly to the position shown in Figure 2', whereupon the beverage from the pipe 2 passes upwardly through the dispensing tube 10 and outwardly to the discharge point.

It is important to prevent passage of air inwardly through the dispensing tube at times when the beverage is not being drawn off, and in order to accomplish this, the dispensing tube is provided with an integrally formed U- shaped trap portion designated at 18 and located outside the display receiver. The tra-p portion 18 terminates in` a downwardly cX- tending discharge outlet 19 and the branches of t-he trap portion are sufficiently long so that when the dispensing tube is released and returns to the position shown in Figure 2, the siphon being broken. a suiiicient amount of beverage will be left in the bottom of the trap portionlS to constitute a seal and pre- -vent passage of air inwardly through the dispensing tube.

. Where it is desirable to hasten the breaking of the siphon and sealing of the dispensing tube after its return to the position oit Figure 2, the moditied construction shown in Figures 5 to 7 may be employed. In this form, each branch of the siphon is provided with an enlarged section 4which may be of circular or other formation, as designated at 20, and located between the top and bottom of the trap portion. By providing the enlarged portions 2() which are ot greater cross-section than the other part ct the trap portion, a greater amount of beverage is left in the trap portion tor sealing and the siphoning action is more quickly terminated. This edectually prevents the siphoning action from drawing all the beverage from the tube, so that a sulficient liquid seal isinsured at all times.

While the invention has been described with reference to certain speciiic structures, it is not coniined to the details disclosed, and this application is intended to cover any modifications or departures coming within the intent of the improvements or the scope of the following claims.

We claim:

l. ln a beverage dispenser, the combination with a display receiver into which beverage discharges, of a dispensing tube slidably mounted in a wall ot thereceiver so that its inner end is positionable in the path of the stream of beverage, said dispensing tube including means located outside the receiver for preventing movement of air inwardly through the tube.

2. In a beverage dispenser, the combination with a display receiver into which beverage discharges, of a dispensing tube slidably mounted in a wall ot the receiver' so that its inner end is positionable in the path of the stream of beverage, said dispensing tube including a trap located outside the receiver for preventing movement of air inwardly through the tube.

8. ln a beverage dispenser, the combination with a display receiver into which beverage discharges, of a dispensing tube slidaably mounted 1n a wall of the receiver with its inner end positionable in the path of the stream of beverage, said dispensing tube having a tra-p portion located outside the receiver and formed integral with the rest of the tube.

4. In a beverage dispenser, the combination with a display receiver into which beverage discharges, ot a dispensing tube slidably mounted in a wall of said receiver, said dispensing tube being formed of glass and having an integral trap portion located outside the receiver to prevent passage of air inwardly through the tube.

5. ln a beverage dispensed, the combination with a display receiver into which beverage discharges, oii' a dispensing tube slidably mounted in a wall of said receiver, said dispensing tube having a trap portion located outside the receiver and terminating in a 'downwardly extending discharge outlet.

` 6. ln a beverage dispenser, the combination with a display receiver into which beverage discharges, ot' a dispensing tube slidably mounted in a wall ot the receiver, said dispensing tube including a U-shaped trap portion located outside the receiver and terminating in a downwardly extending discharge outlet, each branch of the trap portion having an enlarged section located between the tcp and the bottom ot the trap portion.

7. In a beverage dispenser, the combination with a display receiver into which beverage discharges, of a glass dispensing tube slidably mounted in a wall of the receiver, said tube being freely movable outwardly and having means for limiting its inward movement, the tube including an integrally 'formed U-shaped trip portion located outside the receiver and terminating in a downwardly extending discharge outlet and each branch oi' the trap portion having an enlarged section located between the top and bottom of the trap portion.

In witness whereo t', signed our names.
